CENTRIFUGAL LIQUORING APPARATUS SPECIFICATION forming part of LettersPatent NO. 223,539, dated January 13, 1880. Application filed August 8,1879.

To all whom "it may concern:

Be itknown that I, EDWARD E. QUIMBY, of

Orange, New Jersey, have invented certain Improvements in CentrifugalLiquoring Apparatus for employing centrifugal force to effect theliquoring of sugar while it is contained in the molds of a centrifugalmachine, (Case No. 6,) of which the following is a specification.

My improvements belong to that class of apparatus used to conductprescribed quantities of white liquor from the central chamber orreservoir of a centrifugal machine to the several molds arranged in acircle in the basket thereof, without allowing any portion of f5 suchliquor to escape otherwise than through the sugar or magma contained inthe molds.

Mydnvention, which involves the use of movable liquoringboxes, consistsin so hinging such boxes to a fixed part of the basket that the efiectof the rotation of the machine is to cause them to swing outward andmake their outer open faces, which are provided with the usual gasketsof elastic material, bear firmly upon the inner open faces of thesugar-molds, thus making a tight joint therewith.

The accompanying drawings, illustrating a centrifugal machine containingmy invention, are as follows:

0 Figure 1 is a top view, with a portion of the central reservoir brokenaway in order to show the position occupied by the box when swung inwardupon a vertical axis away from the mold. Fig. 2 is a central verticalsection v 5 through the line 00 won Fig. l; and Fig. 3 is a similarsection, showing the liquoring-boxes hinged at their front lower edgesto a horizontal pivot.

The drawings represent the basket A of a 40 centrifugal machinemountedupon the usual vertical spindle B, and containing an outer circleof removable sugar-molds, C. These molds are separated from each otherby the vertical pillars D, affixed to the floor of the 5 basket. Eachpillar is provided with inwardlyprojecting horizontal lugs d, which areperforated to admit the vertical rod 01, which serves as a pivot for theswinging boxes E. Each of these boxes is provided upon its outer openface with the usual gasket 6, of elastic material, and is also providedwith laterallyprojecting ears 0 at one of its outer corners, which areperforated to admit the rod or pivot 01'. r

The direction in which the basket is intended to rotate is indicated bythe arrow in Fig.

l, and it will be seen that the effect of centrifugal force, when thebasket is rotated, is to cause the boxes to swing outward, so that theirgaskets engage the inner open faces of the molds, and are firmlycompressed thereon, making tight joints between the molds and the boxes,respectively.

The machineis provided with the usual central reservoir, F, which has adownwardly- 6 projecting spout, f, for each one of the boxes.

The opening f in the top of each box, for the admission of the spouts f,isconcentrically curved, as will be seen, to preventthe spout frominterfering with the swinging movement of the box.

l The hingin g of the box to a fixed part of the machine serves toretain the box in the proper position with relation to the mold in frontof it, and so defines its path of movement that its gasket is broughtinto contact with the inner edges of the top, bottom, and sides of themold when the machine is rotated. Substantially the same thing may beaccomplished by providing the box with a horizontal axis of oscillation,as shown in Fig. 3, in which the hinge is at the front lower edge of thebox, and the bottom of the box is outwardly and downwardly inclined,thus permitting the box to tilt backward away from the mold when themachine is stationary, substantially in the manner shown and describedin the pending application of F. (1. Matthiessen for a loose tiltingbox, filed May 23, 1879.

It will be advisable in some cases, in order to bring about a sufficientcompression of the gasket by the action of centrifugal force, to loadthat part of the box farthest from the hinge. This may be easily done byincreasing the thickness of the side E{ of the box swing- 5 ing upon avertical axis, or by increasing the thickness of the top E of the boxswinging upon a horizontal axis.

I do not herein claim, broadly, a series of liquoring-boxes looselycontained in the basket 10o of a centrifugal machine, or flexiblyconnected therewith, whereby centrifugal force acts to when swungoutward by centrifugal action its I 5 gasket will be brought intoengagement with the inner edges of the top, bottom, and sides of thesugar-mold in front of it, substantially as and for the purpose setforth.

2. In combination with a centrifugal machine, a hinged liquoring-box,substantially such as described, loaded upon its free extremity,substantially as and for the purpose set forth.
